IMPROVEMENT IN PLATFORM-CRADLES.

Specification forming part of Letters Patent No. 220,857, dated October21, 1879; application filed May 27, 1879.

To all whom it may concern:

Be it known that I, FREDERICK MOHR, of the city, county, and State ofNew York, have invented certain new and useful Improvements inPlatform-Cradles, of which the following is a specification.

In the accompanying drawings, Figure 1.

represents a vertical longitudinal section of my improvedplatform-cradle 5 Fig. 2, a vertical transverse section of the same online a; m, Fig. 1 and Fig. 3, a detail side view of the rocker guidingand retaining plate of the platform.

Similar letters of reference indicate corresponding parts.

The invention has reference to an improved construction ofplatform-cradle that may be changed at will to a crib, and in which theconnection between the body of the cradle and the supporting-platform ismade in reliable and superior manner.

The invention consists of a platform-cradle, the body of which isprovided with Vshaped center-plates having stop-pins, which centerplateswork in connection with symmetricallyfianged guide-plates of theplatform, as will be more fully described hereinafter, and fully pointedout in the claims.

Referring to the drawings, A represents the body of my cradle, whichswings by rockers B on the rails l) of a sup1.)orting-platform, D. Tothe inner side of the rockers are attached V-shaped plates 0, which areprovided with an offset, a, so as to furnish the required space for'theguide-plates E, which are attached tothe platform. At the lower ends ofthe V- shaped plates 0 are rubber-cushioned stop-pins b, which areguided along symmetrically-arranged shoulders or flanges at of theguideplates E. A center-pin, c, of each guide-plate E enters into thevertex of the angle of the V-shaped plate-O of the rocker, and serves toreturn the body of the cradle to its proper central position on theplatform during the rocking motions.

v The symmetrical shoulders or flanges d of the guide-plateE arehorizontal at their lower parts, vertical at their middle parts, and ofsemicircular shape at their upper parts, as shown in Fig. 3. The upperparts of the flanges serve to stop the cradle in its motion in eitherdirection and prevent positively the ac cidental tilting over of thesame to either side. The lower horizontal flanges or shoulders areshort, and leave an opening, d, between the same for the unobstructedswinging of one stoppin until the other is retained by the upper flange.The lower horizontal flanges serve, furthermore, as rests for supportingthe platform when the cradle is lifted for being moved from place toplace. A horizontal stiffening rib or flange, d of the guide-platesconnects the vertical portions of the flanges d, and prevents anypossibility ofdisconncction of cradle and platform.

The cradle may be changed to a crib by any approved locking devicebetween platform and cradle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of arocking-cradle body, A, havingV-shaped cen tor-plates O, with stoppins 1), with a supporting-platform,D, having guide-plates E, provided with symmetrical side flanges. (1,formed of short horizontal parts, straight middle parts, and curvedupper parts, as described.

2. The combination of a rocking-cradlebody, A, having V-shapedcenter-plates with stoppins b, with a supporting-platform, I), having aguide-plate, E, provided with symmetrical end flanges, d, an open space,d, between the lower horizontal parts of the flanges, and a horizontalconnecting shoulder or flange, d substantially as specified.

3. A rocking cradle body, A, having V- shaped plates 0, with stop-pinsat the lower ends, in combination with guide-plates E of thesupporting-platform, said guide-plates having symmetrical end flangeswith short lower stop-shoulders or rests for supporting the platformwhen lifting the same, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 26th day of May, 1879.

FREDERICK MOHR.
